Palenfed May 24, 1932 UNITED STATES PATENT OFFICE BEN AL'IHEIMER, OF UNIVERSITY CITY, MISSOU'RI, ASSIGI\TOR T MYRTLE ALTHEIMER, O]? UNIVERSITYCITY MISSOURI Application filed March 2a,

My invention relates to a method of making radiator shields, and moreParticularly to the methocl 0f making paper radiator shields.

- The invention has among its objects, the

production of a, radiator shield of the kind describecl, which may bemade of a minimum width 0f paper sheet, and which Wlll be simple,speecly, neat, economical, and eflicient and satisfactory for usewhereverv found applicable.

A further object of my invention is t0 so fold a paper radiator shieldthat the same can be readily stacked for 'sfnorage and shipment, andoccupy a minimum of space when so packed.

Many other objects and advantages 0f the method and construction hereinshown and describecl, will be obvious t0 those skilled in 0 the art towhich this invention apperta ins from the disclosures herein given.

T0 this end, my invention consists of' the novel construction,arrangement and combination of parts, and the method employed inobtaining the same, as shown and described, and more particularlypointed out in the claims.

In carrying out the method of forming the preferred embodiment 0:E myinvention, as shown in Figs. l, 4, 7, and 1016 inclusive,

I provide a sheet of relatively thin material such as sized cloth orpaper of rectangular shape 01 outline, it being understood that thispaper should not be 1300 flimsy, ancl preferably be substantiallyimpervious 130 the passage of dust therethrough. A good type 01 paperfor this purpose is the wellknown type of paper called kraft paper, thispaper being relatively tough and able to withstand quite a bit ofhandling, both during the course of manufacture and While in service.

This sheet 0f paper A is preferably marked or scorecl es indicated inFigure 7, in any suitable manner, or the relative distances for folclingmay be made in any other desirable manner so as to facilitate the actualfolding operations upon the sheet.

Tl1e longitudinal 0r side edges of the sheet A are indicated at l-l andare truly parallel edges 2-2 are parallel and perpendicular to theeclges l-l, so as to form a true rectangulatr sheet.

Acljacent the top edge of the sheet are indicated three lines of fold,namely 3, 4, and 5, at progressively increasing distances from the freeedge 2 (top) ancl parallel therewith and witl1 one 21110131161. At adistance qi1ite a bit greater than the spacing between thefirstmentioned three lines, is another line 6, the

distance between the line 6 and the adj acent line 5 indicating thedepth of the top of the radiator shielcl. That is the distance betweenthe lines 5 and 6 Will be increased if the radiators upon which theshields are to be placed are deeper (frorn front-toback) and Will becorrespondingly decreased in case the radiators R are not as deep asthat shown upon the blank. Of course, it is to be anderstood that in allevents, it is better that the t0p of the shield projects beyond thecorresponding front edge of the radiator, so that the dust arisingtherethrough and agitated outwardly can be caught in the dust flange ortrap provided in the shield.

The distancc fro1n the line 6 to the botto-1n 0f the sheet indicatcs theheight of the shield and may be anything less than the actual height ofthe radiator itself, the intermediate line 0f fold 7 being simply forfolding the shield into a compact package.

The manner of folding the top portion of the shield Will now bedescribed, especial refcrence being had to those figures of the drawingswhich particularly illustrate the preferred modification. The first stepin the method is to fold the top edge of the blank sheet upon itselfalong the topmos t line of fold 3, as shown in Fig. 10. Then botl1 edgesof the shcet arc folded at the top oorners, only one corncr being shownin the drawings, the corners being folded inwardly and diagonally andpreferably at an angle of 45 degrecs as shown, along the line 8, asshown in Fig. 11, in which position the top edge 0f the pre viouslyfolded portion is brought down to the line of fold 5, third from the topedge cf the sheet.

Ncxt, the longitudinal edges of the shcet a1e folded inwardly towaid 0neanother, and down onto the previously folded portions, so as to providethe longitudinally extending strips 9, these strips being folded alongthe lengthwise lines of fold 10 until the free cdge 1 of the sheetcoincides with and for1ns an extension of the longitudinally extendingedge of the triangular portion 11 previously formed. By folding in thismanner, the large triangular portion 11 Will be substantially bisectedas shown in Fig. 12.

The next step in the opcration of making the shields is to fold thesheet downwardly on the third innermost line of fold 5, bringing the topof the previously folded sheet to the position shown in Fig. 13.

The next step is folding the portion last folded, and shown in Fig. 13,so as to bring the longitudinally extending edge 12 back onto the sheetuntil said longitudinal edge 12 is positioned transvcrsely to itsprevious position and is brought into rcgistry With the then top edge 0fthe folded sheet (on the line of fold 5), as shown in Fig. 14.

A further step consists in temporarily withdrawing the longitudinallyfolded strip 9 fro1n bencath the folded portions at the top of thesheet, so as to cause a triangular portion 01' tab of four-ply thicknessand indicatcd at 13 to be withdrawn and extend beyond the top of thesheet when the strip 9 is again brought to its folded position, as shownin Fig. 15. In order to facilitate the temporary withdrawal of thelongitudinal strip 9 the previously folded portions are held together byclamping or other pressure, in any suitable manner, and then the strip 9fiipped back lr0m beneath the previously folded portions and againpcnnitted to assu1ne its folded position, as shown in Fig. 15.

Fig. 16 shows the triangular tab portion 13 pasted 01' otherwisesuitably secured in place so as to rctain the corners of the shicld intheir folded position.

lt 1nay again be mentioned that the detailed fold ing opcrationshereinabove described, relat e Only to the forming of the Portion of theshield that Covers the top of the radiator and that the depsndingportions of the shield n1ay be formed or folded in some suitable mannerso as t0 make a neat and compact articlc for sale and sl1ip1nentsomewhat as is shown in Figs. 8 and 9.

T0 attain this end, the bottom edge 0f the sheet may be brought uptoward the top, as on the line o1 fold 7, and then the sides of thesheet are folded toward one another, as shown in Fig. 9 so that onefolded substantially triangular portion overlaps the other portion. Thenthcse' overlapped portions are foldcd upwardly and preferably so thatthe point 14 may be inserted beneath the previously folded top portionof the shield.

The other modifications shown in the drawings illustrate other designsof folding so that the corners Will hat e slightly different appearances, but in all Gases it is t0 be noted that the shield will havea back Wall portion extending downwardly from behind the radiatof, theside edges 0f the same extending forwardly into the room, and having atop 1nember extcnding forwardly over the top of the radiator, and with adownwardly extending flange entirely about the sides and front cf thetop portion, and in adclition there is a dust-catching flange 15provided by the first described step of folding.

I-Iaving thus described my invention, it is obvious that variousimmaterial modifications may be made in the same without departing fromthe spirit 013 my invention; hence I do not wish to be undcrstood aslimiting myself to the exact form, arrangement, construction, andcombination cf arts, 01 the manner of 1naking the same, except aslimited by the art to which this invention appertains, and the claims ashereto appended.

VVhat I claim as new and desire to secure by Letters Patent is 1.
